  • Title: [Morphogenesis of chronic pyelonephritis (electron microscopic study)].
    Author: Kirillov IuA.
    Journal: Arkh Patol; 1980; 42(1):38-45. PubMed ID: 7377988.
    Abstract:
    Examinations of 51 rabbits and 86 patients with chronic pyelonephritis showed the morphogenesis of chronic pyelonephritis to be due to the effect of certain factors. One of them is the capillary-parenchymatous block resulting from the outgrowth of the connective tissue between the tubules and peritubular capillaries. Glomerular sclerosis occurs both periglomerularly (growth of the connective tissue into the capsule) and intraglomerularly (tropocollagen synthesis by mesangiaal cells). Nephrosclerosis combines diffuse sclerosis (the consequence of increasing hypoxia) and focal sclerosis (the consequence of renal tissue destruction during pyelonephritis attacks) which determine the features of regenerative hypertrophy of nephrons and the pattern of pyelonephritic shrinking of the kidney.
